Subject: hwmon: (lm87) Add OF device ID table
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a02c24a321583e7970393488834501e15a69b656;p=linux.git

hwmon: (lm87) Add OF device ID table

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
